01
Who it is for
We support events, temporary sites, productions, operational teams and control rooms that need dependable short-term radio communications or practical communications advice.
Specialist division
CritiCall Communications
Radio networks and communications support designed around the people, site and decisions that matter.
The challenge
A radio is only useful when the network, coverage and channel plan support the people using it. CritiCall designs temporary communications around the operational footprint and the decisions teams need to make.
02
What the service solves
Poor coverage, crowded channels and unclear user groups create avoidable friction. We help clients define who needs to speak to whom, across what area, and how critical information reaches control.

04
Network planning
We review the site footprint, terrain, buildings, user groups, operating hours and control-room needs. The result is a system plan built around real operational use rather than equipment quantity alone.
05
Equipment and user needs
Radio selection, programming and channel structure are aligned with the working environment. Clear handover information helps users understand how the network supports their role.
06
Why choose CritiCall
Our communications work is informed by command and operational requirements. That means the system is designed to support coordination, escalation and decision-making—not simply to provide radios.
Frequently asked questions
Communications
Practical answers for planning your requirement.
01How do you determine how many radios are needed?
We start with user groups, roles, shift arrangements and the operating footprint, then build the equipment requirement from that information.
02When is a repeater useful?
Repeaters can extend or strengthen coverage where terrain, distance or structures affect direct radio communication. The site requirement determines the approach.
03Can you programme radios for different teams?
Yes. Radio programming is part of the listed service range and can support agreed user groups and channel plans.
04Can communications integrate with an event control room?
Yes. Control-room communications are a core part of the service and can be planned alongside event control arrangements.
